SPECIFIG'ATIQN forming part of Letters patent Nq.7o2,11`5, dated rune 1o,- 1902.

i I A.Application Vfiled November 7, 1901- lSerial NoA 81,422. (NomodeLl I i T0 a/ZZ whom traag/concern:

Be it known that I, MARTIN C. SCHWAB, a citizen of the .United States vof America, residing at Baltimore, in the' State of Maryland, have invented certain new and-useful Improvements in Conveyers, ofwhich the following is a specification. l

.This invention Vvrelates to conveyors, and

more particularly to'that classemployed to transmit. merchandise, &c. ,Y from 'the" dierent loors of a storev to the-shipping-department.

" The object of myinvention is to provide a yconveyer by meansof which all motive power heretofore employed isdispensed with, therebyreducing the danger of accidents to a mini` mum; to so arrange and construct the same that it will be exceedingly cheap, durable, and substantial, and -will eiiicien t-ly lperform Tall of its intended functions. l l

Another 'object of Vmy invention, is to provide a conveyer which' in itself will be ornamental, one that may not only be used kas a conveyer, butas -awhotor cold air conductor,

and also a casing forl a lflue, pipes, or other 'features of a building, the appearance'of 'which is objectionable.y

With these'objectsin view and suchl others as may hereinafter appear my invention consists in the particular construction of 'the various parts and in the novel manner of vcombination or arrangement of said parts, all of which will be morek fully described, and specically pointed out-in the appended claims, which are intended to accord in their terms, spirit, and meaningwith the prior state of the art and the existing law. l

In the drawings forming a part of this specilication,Figure l is aside elevation of a conveyer constructed in accordance with my invention, showing theopenin gs or doors for receiving the' packagesythe exit, and ,the receiving-table. Fig. 2 `is-a vertical sectional view of the'inn'ercylinder, illustrating the i arrangement of the spiral and the feeds which vleadfrom theopening or doors to the spiral or conveyer proper.

Fig, 4 isa modified form illustrating a different arrangement of the spiral.

section, which may be used for any special purpose, having .arrangedl thereupon a spiralv iange C, .which extends throughout the entire length,v alsofa series of short spiral flanges D,

which are arranged vat a greater pitch or inper ends of the short spiral flanges D, leading from Vthe openings or doors to approximately near the continuous spiral flange or conveyerpropen'also with an exit registei-,

ing-withfthe lower end of the continuous spiadapted to deflect the article being conveyed the flanges.v l t In Fig. 4 Ilhave shown a modified form of my invention, which consists in arranging the spiral flanges in sections I in reverse with re When this construction',

spect to eachother. is employed,.the lower end of each section should curve up, as at J, `in order to gradufore passing tothe next or proceeding section.

' Modeof operation: Saya package is placedon one ofthe short spiral flanges leading from an opening or a door; Thelaw of gravity will 'then' operateand the package descends down p l the short4 spiral ilange, whereupon it drops to the continuous spirallia'nge and continues its flight until it reaches thegexit at which point it is deflectedupon the receiving-table.

,L I deem the 'foregoingexplanation sufllral flange, which is provided with a guide H, i

` ally takcf up the velocityof the package bel ciently plain 'that the invention will be readily understood by all conversant in such matters.

` v Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is#

l, In a conveyer, a cylindrical vsection,:a

continuous spiral flange arranged uponv thesaid cylindrical section, a seriesr of `short spiral lianges of greater inclination arranged in' juxtaposition tothe said continuous spiral IOO flange, a cylindrical sectionA telescopically covering the Whole, doors and an exit registering with the said flanges, substantially as shown and described.

2. In a conveyer, a cylindrical section having a continuous spiral flange-thereupon, a

series of short spiral anges of greater inclination arranged in juxtaposition to the firstmentioned ange, acylindricalsection adapted to incase the first-mentioned cylindrical section and flanges, and beingprovided with doors registering with the upper ends of the short anges and an` exit registering with the lower end of the continuous ange, substantially as shown and described.

3. In a conveyer, a cylindrical section havinga continuous spiral fiange, a series of short spiral flanges arranged in juxtaposition to the said continuous flange, a cylindrical section i adapted to telescopically cover the first-mentioned cylindrical sect-ion and flanges, the lastrnentioned cylindrical section being provided with doors registering with the upper ends of the said short spiral anges and an exit registering with the lower end of the conti n nous spiral, and a deflection at the end 0f the continuons spiral Iiange, substantially as shown and for the purpose set forth.

In testimony whereof I hereto affix my signature in the presence of two Witnesses.
